2Claims. (Cl. 30-.30)

Thi inventi elates vi used by a person in cutting hair. i

The object ofthe invention is .to provide a haircutting device whichwill enable the person to cut or trim his ownhair or anothers hair.

Another object of the invention is to provide a haircutting device whichcan be easily regulated in order to cut hair at any desired length andwhich can be readily assembled and. disass mb fl a o A further objectofthe invention is to provide a haircutting device which is extremelysimple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of thefollowing description.

In the accompanying drawings, forming a part of this application, and inwhich like numerals are used to designate like parts throughout thesame:

Figure 1 is a front elevational view of the haircutting device,according to the present invention;

Figure 2 is a side elevational view of the haircutting device;

Figure 3 is a rear elevational view of the device;

Figure 4 is an enlarged sectional view taken on the line 44 of Figure 1;

Figure 5 is a rear elevational view of the blade holder;

Figure 6 is a front elevational View of the support member;

Figure 7 is a side elevational view of a modified form of thehaircutting device.

The free end of the rear leg 2| is provided with a plurality of spacedtapered teeth, 21. The teeth 21 are arranged intermediate-the ends ofthe rear leg 2|, and an ear 28 is provided or arranged on eachside oftheteeth2l.

Arranged contiguous to the rear surface of the rear leg 2| is a holder29 which is Shaped to de'-'- fine a compartment 3|) for receivingtherein a blade 3|, such asa single-edge razor blade. The

; top'ofthe'compartment' 39 is open wherebythe blade 3| can beremoved,and replacedwhen' dulled by continued use. A slot 32 is arranged in thebottom of the holder 29 so that a portion of the cutting blade 3| isexposed therethrough, and this exposed portion of the blade 3| coactswith the teeth 21 to cut or trim the hair as the device is moved by theuser.

Arranged on each side of the holder 29 and formed integral therewith isa channelway 33 which snugly receives therein the ears 28 of the supportmember in order to maintain the holder and support members in alignment.The holder 29 is provded with a slit 34 therein which enables the userto insert the thumbnail or a pointed object therethrough in order toloosen the blade 3| from the holder when the blade is to be removed fromthe holder.

A means is also provided for adjustably connecting the holder 29 to theguard 20 whereby the length of cutting by the blade 3| can be regulated.This means comprises a securing element 35 and the securing element 35includes a Y threaded shank 36 which projects through a slot Referringin detail to Figures 1 through 6 of the drawings, the numeral 20designates a substantially U-shaped support member which may befabricated of any suitable material. The support member 20 includes afront leg 22 and a rear leg 2|, the front leg 22 having its lower endcoiled or rolled as at 23, the rolled portion 23 defining a thumbsupport.

For maintaining the front leg 22 and the rear leg 2| in their properspaced relation, a pair of suitable braces 24 extend between the pair oflegs and are secured thereto. The braces 24 are necessary if the supportmember 20 is made of a strip of material such as copper. However, thesupport member may be fabricated of a suitable plastic and such amodified support member is indicated generally by the numeral in Figure7. In fabricating the device of Figure 7, the support member 25 isformed with suitable side walls 26 which serve to brace the front andrear legs thereof and such side walls eliminate the necessity of usingthe braces 24,

3'! in the holder 29' and. through a registering threaded aperture 38 inthe rear leg 2| of the support member 23. The securing element 35 isprovided with a knurled head 39 which enables the user to readily rotatethe securing element 35. The upper end of the holder is provided with arolled or coiled portion 49 and the coiled portions 49 and 23 areadapted to be gripped by the users fingers in manipulating the device.

From the foregoing, it is apparent that a haircutting or trimming devicehas been provided which will enable the user to cut his own or anothershair. The user inserts the blade 3| into the compartment 3|] of theholder 29 so that the cutting edge of the teeth 3| project out of theslot 32 in the bottom of the holder. Then, the rear leg 2| of the holder29 is positioned contiguous to the holder 29 and the leg 2| is arrangedso that its ears 28 fit into or are seated in the channel ways 33 whichare spaced from and part of the holder 29. The holder is arranged sothat the cutting edge of the blade 3| 3 extends to the desired positionwith respect to the teeth 21 and the securing element 39 is thenprojected through the registering openings 31 and 38 to maintain theholder 29 immobile in its adjusted position on the support member. Then,the user grips the device so that his fingers are in engagement with thecoiled portions 23 and 40 so that the device can be moved along to trimor cut hair. Thus, it will be seen that the device is ruggedlyconstructed and by using the device, the hair can be cut in a neat andefiicient manner.

While I have shown certain embodiments of my invention, this is by wayof illustration only, and I consider as my own all such modifications inconstruction as fairly fall within the scope of the appended claims.

I claim:

1. In a hair cutting device, a U-shaped support member including a frontand rear leg, braces extending between said front and rear legs andsecured thereto, the free end of said front leg being provided with acoiled portion defining a thumb support, a plurality of spaced teetharranged on the free end of said rear leg, a holder arranged contiguousto said teeth, the upper end of said holder being provided with a rolledportion, there being a compartment in said holder, a blade positioned insaid compartment, the top of said compartment being open, said holderhaving a slot communicating with said compartment for exposing a portionof said blade, coacting means on said holder and support member formaintaining said holder in alignment, and a securing element adjustablyconnecting said holder to said rear leg.

2. In a hair-cutting device, a support member including a front and rearleg, the free end of said front leg being provided with a coiled portiondefining a thumb support, a plurality of spaced teeth arranged on' thefree-end of said rear leg, a holder arranged contiguous to said teeth,said holder being provided with a rolled portion, there being acompartment in said holder, a blade positioned in said compartment, thetop of said compartment being open, said holder having a slotcommunicating with said compartment for exposing a portion of saidblade, coacting means on said holder and support member for maintainingsaid holder in alignment, and a securing element adjustably connectingsaid holder to said rear leg.
